        Current C1/C2 compiler time tracing is old and rusty:
         - separate VM options for C1 and C2 compilers
         - C2 tracking ignores CompilerBroker (mostly), and doing the tracking on its own
         - bailouts and invalidates are ignored in time tracks
         - significant parts of compiler code is not timed accurately

        We need to fix that for any future compiler performance work to succeed.
        (Patch follows).
